I've come to a conclusion that a weekly, cold reboot is a required maintenance task with the/my DVR+. The pattern is consistent. Following a cold reboot, everything is fine. But as recordings accumulate and are later deleted I have noticed the following: As time passes, disk space isn't reclaimed through the DVR+'s normal housekeeping routines. Even though recordings are deleted and the history is cleared, the disk usage percentage doesn't drop. The internal clock starts fluctuating on a daily basis. After several days of this the On/Off button on the remote becomes inconsistent. When I press the button to turn it on, the red standby light blinks off, then on but nothing happens. I push it again and the unit fires up. Frequently, the TV doesn't turn on with the DVR+. Then, the coup de grace occurs when I try to use the jump button to jump forward (I don't know if it is the same for jumping back)--I press the button and the recording jumps forward, but the movement is jerky, not smooth and fluid like it should be. I press it again and nothing happens. When I press it a third time it jumps forward. Then it starts a cycle of jumping forward on one press, nothing on the next, forward jump on the subsequent press, then the process repeats every time after that: Jump forward, no action, jump forward, no action, etc.
When I see this I know that I have to do a cold reboot, and that fixes everything but the EPG needs to repopulate after the reboot. This evening I knew I had to do a cold reboot when I saw the intermittent jump behavior. Prior to that I had noticed that the disk usage percentage was stuck at 9%, even though I had deleted several hours of programming I had been viewing over the last several days. Now to be fair, some of this programming dated back to November, so I don't know if that played a part in this. After the cold reboot, the disk usage percentage dropped to 4% and all behavior was back to normal.
Could I report this to the support people at CM? Yes. Will they suggest anything other than doing a cold reboot? No, unless they suggest a factory reset, which is not an option if the DVR+ isn't in the middle of its version of a BSOD tantrum. So a cold reboot it is, which also requires a reset of the time, which I tend to set 30 seconds fast. My nerd cred may not be the highest, but I do know that this is a software/firmware problem.
Years ago I purchased an NLE which was also buggy. There was one software update I was able to download, but after that there was nothing until a new version was released, which I would have been required to purchase. Fortunately, CM can't make me buy a new DVR+ to get passed the buggy version(s) that they won't fix. Unfortunately, I'm basically cleaning up their mess by doing a weekly cold reboot until they release a new firmware update that most likely won't fix the problem, either. Request: Channel Master, please add a reboot option to the menu (and please put it in a place that is both hard to find and requires drilling down through several layers of menu items to get to) so it can be done without physically pulling the power connection out of the unit or the outlet.
